Michael, Bill, thank you very much: DONE!!! I have put the handle on fire (on a stove in the kitchen

) just a minute and the resin became softer and the handle can be simple removed!! The blade seems good. Now i will try to put in acid (lemon or vinegar) the handle and just see what happens. Anyway now i need a tulwar handle: nobody here has one?
Thank you very much for the help
P.S. i will post some pics
